I agree with both that it will make life easier and harder. I think it will make life easier because of global worming so that when the pullotion comes out through the car it goes up in to the sky and there won’t be any traffic it would be cool to make these kinds of cars. It will also be easier so that people can drive easily. I think it will be hard because it would cause lots of accidents to happen like crashing in to buildings or falling down on the ground. I am mostly close to the harder part because I don’t want our country to be destroyed but it could be possible who knows.

Hi,
It depends on what kind of fuel the hover car runs on. If it ran on water I think it would be better than if it ran on toxic gas. But I think the hover cars would probably be run on gas so I think it would make life the same because if they are hovering instead of driving, the only change would be you’d be hovering above the road.
Caitie

I agree with Caitie but I think that hovering cars would be a bit worse because if it uses gas it can blow toxic gas into the sky which makes the air dirtier . It would cause as much pollution as a normal car. But if it uses some source of clean gas it would help the air be more cleaner.

It depends on how much pollution they would make, but mostly it would make life easier because, as Andrea said, there wouldn’t be that much traffic, and there would be enough streets right now, because some cars could, still go on the road. The problem wold be that there might be air traffic, and there would be car crashes, only they would be in the sky, and would more people dying because the car fell from the sky, but it might also cause less traffic.

I agree with Hannah it does depend on how much pollution they would make, but the bright side is there would be less traffic but what if there would also be air traffic? then people would have car crashes only in the sky, and it would be dangerous because you would fall from a car crash, and it would make as much pollution as a normal car, and if a different kind of gas would be used it would be better for the air. And there is also one thing that no one has mentioned, if you used hover cars then there wouldn’t be any police to make sure you are going against the rules and then there would be chaos and lots of car crashes.

Hi 6ss,
I think that it would make it harder because you can’t see below and above and you might crash and you don’t have a runway and if you had the car and the runway it would be very expensive. Another reason of why you shouldn’t have flying cars is why should we make the car fly there’s not much use to it except there is no traffic. The last reason is you are actually putting your lives in risk because if you crash and fall you die if you run out of oil you die if the engine stops working by some how you die!

I think it will be better to have hovercrafts becasue then you can hover across the sea. There is also no traffic and that means you dont have to wait hours in traffic. Its also a lot easier to travel around countries. It could also be bad because maybe some people couldn’t afford the new type of cars. I also agree with Melis that there will be a lot of more car crashes. It is also easy to do take down building just like 9/1/1 becasue you dont have to high jac a plane you can just crash you hovercraft into a tall building.

I think it will be better to have flying cars, if it waste a less than cars and because if you still use cars you are still wasting fuel and polluting. And if you use flying cars you don’t need to use that many ships and maybe air planes because people can just fly in their flying plane. You will waste less fuel because airplanes waste a lot of fuel and pollute and ship also do the same thing, but ships sometimes spill oil like big oil spills which kill millions of fish, but if a flying car breaks down or crashes it won’t spill as much oil as a gigantic ship or plane.

I think it would be better to have hover cars because it wound’t waste any fuel or oil. It is also easier to travel because instead of taking a plane or a ship you can take your hover car. Another reason why you wouldn’t waste fuel and oil is because if you take a air plane or a ship it would waste a lot of oil and pollute, and because someone times ships and air planes crash into sea so it would kill millions of fish, like the oil spill from gigantic ships.

I think it might be better if we had hover cars. My positive thinking is…..hover cars do not use up our fossil files which is something we are running low on. Hover cars would mean we would not have to go o boats which make some people seasick! Hover cars would mean that there would be no traffic jams because you could hover over the cars in front of yours.

The negatives are hover cars will use electric which will also someday run out, and trust me we rely on electricity! Hover cars would be used for everything so much that in the end no one would have jobs at the airport or at th port! There would not really be any routes, everyone will just be flying randomly! There would be more accidents because people are trying to show of about how their car can do a backflip!

In conclusion I think we would be better off just going back to our old wagons! Yes, there would be more of a chance you will get robbed but there is a less amount of chance someone will crash into another car or someone try to do something really silly!

Hi Billy,
aircraft always must fly in designated routes, otherwise there would be chaos in the skies. When you take an airliner, it always follows a route. Air routes maintain safety and order, so aircraft will not crash into each other. Also, if there is a slow propeller plane like this, there is a very high chance of stalling and crashing if you are an inexperienced untrained pilot. So training is very important. If you read my comment , you can find out more.

Hi,
I agree with Caitie and Tammy. I want to add on a bit. I think hovering cars will pollute the air and it will make us sick with dirty gas. Like Caitie said, it depends on what gas the car use, but I think hover cars need a lot of toxic gas to fly.
It will make life easier by driving easily and no traffic jam. You can arrive at the place just in time.
My answer is both.
It should be both because it’s not all bad but not all good. Everything has bad stuff about it and good stuff too.

Hover Cars would make life soo much easier because if you need to get somewhere quickly, you just have to fly your car. It would also make life hard because there might be so much buttons that you get confused. I think its better for people to get this kind of car as long as they just don’t use it as some kind of play toy. If people use it as a play toy, they might as well distroy somebodies life. If they do come out people shouldn’t use it so much because it takes up energy and so there will be more pollution.

I agree with Billy that people might show off and make the poor peoples life miserable.
Actually maybe it might not be a good thing to have this kind of car in this world because so many bad things can happen because of this car.

So what i’m going to chose is….. WE SHOULDN’T HAVE THIS CAR IN OUR WORLD.

I think hover cars would make life easier and harder. It would be easier because cars wouldn’t have to ride on roads. This would mean fewer traffic jams. It would make life harder because if we use gasoline or diesel engines as they would pollute the air. If we use solar power, they would not pollute. We are already polluting Earth. If we pollute more, the Earth would be destroyed.

I guess it depends what sources you use. If it is a source that is durable than it hover cars will help our life because we will be able to fly and we might be able to be more creative. Also if the hover cars will pollute the air it will be great because we can fly any time we want and we are not damaging the earth. Though I think it is good to have hover cars because then you will see the world in different angles and you’ll see different things you never saw before. I think it’s good to see in different angles and mostly we are on the ground so we only know those techniques but if we are on the sky we will find more techniques that will improve our life. Also the traffic might be not that bad because you are flying and it is easier too see where other people are going. Actually, I think it should be really creative if we make flying traffic lights so we can crash on to each other. Also we can have a lot of fun! Even now, when we have so many things invented, we don’t really have an invention about flying without getting tickets, etc. If we have flying cars, then we will be free to go everywhere with us flying! It will be really exciting. Thus, first the hover cars will be really expensive but then it will cost like the normal cars because of other creative inventions! Conclusion, I think have flying cars are very creative and useful so I think we should have it if we use durable resources. Also if we are really safe in the sky!

I agree with Caitie – it depends what the car runs on. If it runs on the same thing that regular cars run on, I don’t see the point of having a hover car only because it flies. Just a thought though: it’ll be cool if the car ran on our waste and all the stuff we throw away such as plastic. That way, we could recycle and still get a benefit out of it.

Anyway, I disagree with most people that there will be less traffic because if most people buy a hover car, there will be more air traffic and less land traffic. Although, I do agree with people that crashes would be more dangerous because the following things might happen if we have a car crash in the air:

• The car might drop and land on somebody or something (example: another car)
• It might smash into a building

So I think it’s as dangerous as a car crash on land apart from the fact the car can drop which makes it even worse. I also disagree with anyone that says there won’t be any pollution because even though it’s in the sky, we still breathe in the same air.

In conclusion, I think that having a hover car is not an advantage to anybody.

I think it might be better because it will cause less traffic in the future and it will also make it easier to travel to different country’s. But it well make it harder to get your licence because flying is harder than driving a car. But another bad thing is that if the car is not a concept it will cause even more pollution than there is already and that will destroy the world way faster than it is now.

Hi 6SS,
I think in someways hover cars will make life easier because it can save time for travelling one place to another place and there will be less traffic on the street. But the bad thing is that will cause more pollution in the air which will make the global warming situation even worse .In addition when there is an accident in the air it will be like a plane crash and it will cause a lot of damage and i think that it would be more expensive than a car crash.
Pan

I agree with victor but I also think that the hover cars will pollute a lot more than a normal car so it would be worse for the environment. If you crashed with a normal car on the ground you would have a big chance of surviving but if you crashed in the air you would fall from a really big height and would probably die. If you had a hover car you would be able to get to places a lot faster.

Hi
I think hover cars won’t really make a difference because what is the difference between flying in the air or on the ground I don’t really think it is a difference because in the air you can see only see the city and on the ground you can see the world go by.
It can make the world polluted like some other people says. Because they will need more gas (or maybe some kind of air gas).
My perspective is maybe we should try not to use to much invention with electricity

Hi,
I know a lot about these things because I am really interested in engineering. There are many pros and cons about this. If this really happens, it will make a massive difference throughout the world and cause a shift in the course of history, so it is related to Where We Are in Place and Time. One thing that I would like to make clear is that hover car or flying car is more generally used in science fiction. The more realistic term is roadable aircraft. Such aircraft have been designed, such as the Terrafugia transition, or Rutan’s Model 367 BiPod. However, as these aircraft are also designed to be able to act as cars, they cannot fly at a speed above Mach 1.

There is a TED talk featuring Burt Rutan. He is a modern pioneer of aviation, developing the Model 367 BiPod, the VariViggen and also White knight and Spaceship One.

I disagree with most people that there will be more air traffic, because this will change many laws. Most people say that there will be more air traffic, but on some days some cars can hover and some drive normally, and on other days they can swap. I figured this out a long time ago.

There are many things to consider for a hover car, such as fuel, propulsion and aerodynamics. It could run on nuclear energy, but that would be pretty risky if you cannot contain it. However, radioactivity can be blocked by some materials, such as lead. It could run on oil, but it would not last for long especially if the car needs to fly and cruise at a speed of Mach 1.2 or below.

Many things can cause an airborne vehicle to crash. It can be mechanical error or human error, two factors to consider when designing heavier-than-air flying machines. There could be an autopilot to handle the vehicle while cruising. However, hover cars must have a very accurate autopilot because cars and helicopters tend to turn/bank more than airplanes.

An airplane flying system is very different from a car driving system. When you drive, you obviously cannot climb or drive(up or down) or do a roll/yaw. Whenever airplanes bank (‘turn’), it uses both the rudder and the ailerons; The pilot turns the control stick or yoke, it only controls the ailerons, which makes it roll. To bank, the pilot needs to also move the rudder foot pedals.

There is also the matter of propulsion and aerodynamics of this aircraft. If it used normal propellers or jet engines it would not be able to hover, unless the aircraft is designed as V/STOL or tiltrotor/tiltjet/tiltwing. A tailsitter design would be just uncomfortable. If this design does not have a good wing design and a aerodynamical body/fuselage, it will not be able to have lift, resulting in too much drag and an imminent crash. Also, to drive as a car, it would need to be able to stow it’s wings because when it drives on the road it will have a less likely chance of crashing.

This would cause a revolution, because it would change parking lots, routes and traffic density. To maintain order and not have these aircraft flying everywhere, there should be a designated route if you want to go to some place. Commercial jetliners follow air routes, did you know? For example, if there is a flight from Beijing airport to London Heathrow, you either fly the northern route, or maybe the southern route. You don’t just fly north, than bank south. Did you ever think what would happen if there were no routes or roads?

When a plane is coming in to land on final approach, it has to follow a special route to land otherwise it could crash or stall. When it is flying in, it reduces power and leaves the engine to idle, and then when it is very close to the runway, it opens power just for a brief moment to help it flare without stalling, then when it touches down it immediately cuts power, deploys wheel brakes and air-brakes, and then reverses the engine.

So, I think that there are both pros and cons that we need to discuss more about on roadable aircraft. In general, I think it would be a good idea to have roadable aircraft, though it would be not much different from having a variable-geometry aircraft(swing-wing).

You can’t just turn on you aircraft and then takeoff-that would create the possibility of a crash if you are not a trained and experienced pilot. Training is very important. To get a flying licence (yes, pilots also need licences to fly!!), they must attend ground school, flight school, spend time in a simulator, and make their own solo flight. It is really hard to be a pilot because you must multitask in order to fly you plane. For example, you must need to know what is ahead of you that you cannot see on you screens, like a flock of birds (bird-strikes are very dangerous, not joking!) and you must also check your screens to know how much fuel you have left, and check your flight plan. Pilots must be good at math because they have to calculate the distance and fuel amount to determine how much power can be added to the throttle etc. Also, before they take off, pilots must submit a very complicated flight plan involving math, to the ATC tower or else they will not be allowed taxi clearance, let alone takeoff clearance!

I think if we have hover cars the world will be a better place and a worse place. There are some positive and sides to it, but there are also negative sides to it.

It will be a better place because a hover car will be a combination of a plane and a car we don’t need to make them separately anymore and also it’s better because there will be less CO2 so the air will be more clean and good for environment. It’s also good because if we are in the land there are lumps and you might feel car sick but if we go in the air there are no lumps so that might be helpful. The good thing about hover cars is that there will be no traffic because you are flying. And also you will arrive faster to work or school because there are no roads and there are no places that you can’t go in or go close to it. It’s also very useful when natural disasters occur. For example, if an earthquake and a tsunami occur you can fly and escape easily.

But I think it also has bad effect because the cars we don’t use are going to be abandoned and not be used forever so there will be a lot of junk in countries. Also there will be a strong worry if we have too many hover cars in the sky at once and an accident happens or if the hover car breaks down, it will fall down from the sky and hit other people who are on the ground. Another negative part of the hover car is people would not walk and they will start to be lazy. After a few years we might become really fat and have obesity if we keep on ridding hover cars every day.

Hi Yuki,
you mentioned no roads. We are talking about a hover car/roadable aircraft here. This poses a question. There is such a thing as air-to-air refueling, but then how could the oil tanker aircraft refuel? maybe they could be VTOL aircraft capable of hovering.

I just have one more thing to say. Non-retractable landing gear cause more drag. If you compare today’s airliners, like the B777 to the airliners of the early 20th century, modern airliners fly faster and higher not only because they have pressurized cockpits and jet engines, but also because of retractable landing gear. If we could develop a roadable aircraft that had retractable landing gear, than that would be great. However, you must take into consideration that if the hydraulics or electrics fail, than the landing gear might not be able come down.

Also, I just thought that VTOL aircraft are good for the environment, because they can takeoff and land like a helicopter, so that eliminates the need for runways, resulting in trees not being cut down.
